Ratio of cache hits to cache misses for the Memcached node excluding set operations. Reported as a percentage.

Items

Items

memcache.googleapis.com/node/items

Count of items stored in the Memcached node.

Memory Usage

Memory Usage

Unused Memory

memcache.googleapis.com/node/cache_memory

The memory usage of all of the nodes in your cluster, broken down by:

used memory

unused memory

Memcached stores items in memory in chunks and slab classes. Depending on your item size distribution, it's possible that some memory will never be used. See the open source Memcached documentation to understand how memory management works in Memcached.

Operation Count

Operation Count

Get Operations

Delete Operations

memcache.googleapis.com/node/operation_count

Count of the operations sent to a Memcached node, broken down by the response type:

get operations

set operations

delete operations

Received Bytes

Received Bytes

memcache.googleapis.com/node/received_bytes_count

Bytes of memory received by the Memcached node from the network. These are the Memcached requests coming from client VMs.

Sent Bytes

Sent Bytes

memcache.googleapis.com/node/sent_bytes_count

Bytes of memory sent by the Memcache node to the network. These are the Memcache responses.

Uptime

Uptime

memcache.googleapis.com/node/uptime

How long the Memcached node has been up, in seconds.

Known Issues

For the operation_count metric, the gat/gats command currently does not
show up in the Cloud Console or in Cloud Monitoring. OSS Memcached
doesn't update its get counters on gat/gats at this point.

For the operation_count metric, the touch command does not currently get
reported.

For the operation_count metric, cas operations are reported under set
operations.
